A deer has been found with epizootic hemorrhagic disease, known as EHD, the Michigan Department of Natural Resources and Michigan State University announced. It's the first confirmed outbreak this fall.
The state agency said a type of midge spreads the virus that causes EHD. It said the disease doesn't affect humans and that venison from infected deer is safe to eat.
"Deer can suffer extensive internal bleeding, lose their appetite and fear of humans, grow progressively weaker, salivate excessively and finally become unconscious," the DNR said in a statement. "Due to a high fever and extensive internal bleeding, infected deer often are found sick or dead along or in bodies of water."
The DNR said it has received reports that between 25 and 50 deer have died in the area.
